Looking to make more power with your 2018-2022 Mustang GT? Well we have what you're looking for. Lethal Performance offers several different handheld programmers / flash tools for your 2018-2022 Mustang which include brands such as SCT, Lund Racing, Ford Performance, Diablosport and HP Tuners. Some of these devices come with pre-loaded base tunes for your vehicle. However if you're looking for optimum performance you're going to want to go with one of our Lund Racing custom tuned devices. Lund Racing exclusively tunes on their Lund Racing Ngauge and SCT devices. Their custom tunes are guaranteed to put a smile on your face. How their custom tuning works is once you place the order for the device with tune or tune by itself we email you a link to the custom tune request form. You'll fill out the form with all of your vehicle's info and mods and from there Lund Racing will build your custom tune. The tune will either be emailed to us for us to load on the device before it ships or it gets emailed directly to you for you to load on your previously purchased device. Not only can Lund Racing provide tunes for simple bolt-ons but they also have the ability to remote tune your vehicle for other power adders such as superchargers, turbo kits, aftermarket cams, nitrous and E85 / Flex fuel. If you have any questions regarding any of the devices or custom Lund Racing tunes contact your Lethal Performance sales associate today.
